딜라토미터(열팽창율측정기)

Unitherm™ 1000

온도범위/ 측정범위

• -150°C ~ 500°C [Low temperature]
• RT ~ 500/1000/1200°C [High Temperature]

This instrument is a fully computerized dilatometer system designed to measure dimensional changes of a specimen brought about by changes in its thermal environment. Linear thermal expansion coefficient, annealing characteristics and other physical or chemical changes manifesting themselves in a change of linear dimension can be precisely determined. Studies of processing parameter as reflected by dimensional changes of the material can be studied in great detail through duplication of thermal cycles and rates used in the actual process. Due to the flexible programming of thermal cycles, complex processes can be easily simulated.

The digital displacement transducer used in the system is an absolute device with no periodic calibration requirements. It is free of short term drift and long term changes, as its accuracy is based on a very stable internal glass grating whose movement is optically monitored.

• -150°C furnace, 1200°C furnace, polymer furnace
• Dual furnace option
• Up to 4 samples
• ASTM

Up to two furnaces can be configured on the same platform. Additional furnaces can be easily exchanged by the user.

The plate type furnace (Model 1020) is designed to test polymers and other low thermally conductive materials by placing the flat sample in direct contact with the heating/cooling surface to minimize thermal lag during controlled rate heating/cooling.
